X-Git-Tag: v2.6.23-rc3~77
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=88ffc3505988196ef5cfdc0278ad89025c2a7b1a;p=~emulex%2Finfiniband.git

Revert "genirq: temporary fix for level-triggered IRQ resend"

This reverts commit 0fc4969b866671dfe39b1a9119d0fdc7ea0f63e5.  It was
always meant to be temporary, but it's generating more useless noise
than anything else, and we probably should never have done it in the
generic kernel (only had the people involved test it on their own).
